Homotopy equivalences and Grothendieck duality over rings with finite Gorenstein weak global dimension

Junpeng Wang, Sergio Estrada

Let $R$ be a ring with Gwgldim $(R) < \infty$ . We obtain a triangle-equivalence $K (R - GProj) ≃ K (R - GInj)$ which restricts to a tri…

One-sided Gorenstein rings

Lars Winther Christensen, Sergio Estrada, Li Liang +2

Distinctive characteristics of Iwanaga--Gorenstein rings are typically understood through their intrinsic symmetry. We show that several of those that pertain to the Gorenstein glo…
